In this study, the expressions of Beclin1 and LC3II/LC3I were higher following the overexpression of miR-1182 and let-7a; however, this finding can be reversed by the overexpression of NUAK1, suggesting that the up-regulation of miR-1182 and let-7a could improve CCA cell autophagy. Here, BECN1 is linked to cholangiocarcinoma.
